I'm trying to remember all of the details of your situation, do excuse me if the following don't apply. Can you do any of the following jobs? If I was in your position, I would be doing a lot more than trying to mystery shop.
-Walmart greeter?
-Customer service at a supermarket?
-Work at home options like:
Teaching English via Skype
Listening to audio and transcribing
Online personal assistant
Fiver jobs
Amazon mechanical turk
Have you considered moving to a lower cost of living area and renting a room? Maybe near an area that is more urban or has more shops? I just looked up renting rooms where we are. In PA, you can rent a room in central PA for $400 with all utilities included. There are a ton of shops and local transport options for free. There are lots of churches that offer assistance with all kinds of things around here too. They have food pantries and clothes, etc. I'm just familiar with the area near us, but if rooms are $400 here, they can be lower elsewhere.
There has to be some other option. Your current situation is untenable.
